If the board is a PCI board, then it will default to setting irqs to PCI/ISAPNP which isn't what you want. You want irq5 on legacy isa. If Alsa can't trigger and detect an interrupt it won't find the sb16. Dos may work because unlike Linux it doesn't attempt to reconfigure bios32 and ESCD/PCI space. Just a thought. -- Kerry Hoath: kerry at gotss.net kerry at gotss.eu.org or kerry at gotss.spice.net.au ICQ: 8226547 msn: kerry at gotss.net Yahoo: kerryhoath at yahoo.com.au
